c#批量上传图片到服务器示例分享

　　这篇文章主要介绍了c#批量上传图片到服务器示例，服务器端需要设置图片存储的虚拟目录，需要的朋友可以参考下

 public void UpLoadFile(string srcurl, string imagesPath, List<string> files)
 {
     int count = ;
     foreach (string imageName in files)
     {
         string name = imageName;
         string url = null;
         //+  加号特殊处理
         if (name.Contains("+"))
         {
             url = srcurl + "name=" + name.Replace("+", "%2B");
         }
         else
         {
             url = srcurl + "name=" + name;
         }
         FileStream fs = new FileStream(imagesPath + name, FileMode.Open);
         byte[] data = new byte[fs.Length];
         fs.Read(data, , data.Length);
         fs.Close();
         HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
         request.ContentType = "image/jpeg";
         request.Method = "POST";
         Encoding encoding = Encoding.UTF8;
         request.ContentLength = data.Length;
         Stream requestStream = request.GetRequestStream();
         requestStream.Write(data, , data.Length);
         requestStream.Close();

         HttpWebResponse response = (HttpWebResponse)request.GetResponse();
         StreamReader streamReader = new StreamReader(response.GetResponseStream(), encoding);
         string retString = streamReader.ReadToEnd();
         streamReader.Close();
         Console.WriteLine((count++) + "/" + files.Count);
     }
 }

服务器端代码：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Web.UI;
 using System.Web.UI.WebControls;
 using System.Net;
 using System.Text;
 using System.IO;
 public partial class upload : System.Web.UI.Page
 {

     protected void Page_Load(object sender, EventArgs e)
     {
         string fPath = Server.MapPath("服务器端图片存储的虚拟目录名称");//得到虚拟目录的真实路径//检查存储目录
         if (!Directory.Exists(fPath))
         {
             Directory.CreateDirectory(fPath);
         }
         string name = Request.QueryString["name"];//得到文件名
         HttpUtility.UrlEncode(name, Encoding.GetEncoding("UTF-8"));
         if (name != null)
         {
             if (!File.Exists(fPath + name))
             {
                 System.IO.Stream stream = Request.InputStream;
                 byte[] buffer = new byte[stream.Length];
                 FileStream fs = null;
                 try
                 {
                     fs = new FileStream(fPath + name, FileMode.Create);
                     while ((stream.Read(buffer, , buffer.Length)) > )
                     {
                         fs.Write(buffer, , buffer.Length);
                     }
                 }
                 catch (IOException ioe)
                 {
                     Response.Write(ioe);
                 }
                 finally
                 {
                     if (fs != null)
                     {
                         fs.Close();
                     }
                     stream.Close();
                 }
                 Response.Write(name + "<br>");
                 Response.Write(File.Exists(fPath + name) + "<br>");
             }
          }
         Response.Write("上传完毕" + Directory.Exists(fPath) + Path.GetFullPath(fPath));
     }
 }
